Question
upsilon^rightarrow = (12m/s, negative y - direction) Express your answers using two significant figures. Enter your answers numerically separated by a comma. alpha^rightarrow = (22m/s^2, 38^degree below positive x - axis) Express your answers using two significant figures. Enter your answers numerically separated by a comma. F^rightarrow = (70N, 43.7^degree counterclockwise from positive y - axis) Express your answers using two significant figures. Enter your answers numerically separated by a comma.Explanation / Answer
1. v=12 m/s -Y direction (angle =270 degrees)
Vx = vcos(270)=0
Vy = vsin(270)=-12
2.a = 22 m/s^2 ,38 degrees
ax = acos(-38)=17.33
ay = asin(-38)=-13.54
3.F=70 N , counter clock wise direction +Y axis
counter clock wise direction +Y axis , means 90+angle from +X axis
Fx = Fcos(90)=70
Fy = Fsin(90)=0
